BCM4359

Today Broadcom took the lead by announcing two new Wifi combo chip solutions meant for the smartphone and tablet market. The BCM4359 is a high-end 2x2 MIMO solution for high-performance smartphones, while the BCM43455 is an updated 1x1 MIMO 802.11ac for mass market phones. Taking a closer look at the BCM4359, we see several innovative new features, the most characterizing one being the inclusion for the first time of Real Simultaneous Dual Band (RSDB). RSDB enables the chip to connect to both 2.4GHz and 5GHz bands simultaneously. This is achieved by doubling up on the baseband processors on the combo chip. Broadcom uses ARM Cortex R4 as the processing units of the IC, and the 4359 uses two of them. What this enables is a...
